Some people do it for free because at the time they believe, yes. They usually enchant people by giving them a sense of belonging, similar to what some christians have been seen to do.
Even if the person realizes that they've been lied to, it's hard to get away because it would mean losing all your friends, perhaps your job, etc. Much like a cult, I have seen people getting chased if they try leaving. This is a very complex issue.
sounds just like the trans-trenders, feminism, religeons and racist idealogs. I agree its just like a cult.
